Spinal Cord Stimulation
Status Active Medical and Behavioral Health Policy Section: Surgery Policy Number: IV-74 Effective Date: 03/23/2015 Blue Cross and Blue Shield of Minnesota medical policies do not imply that members should not receive specific services based on the recommendation of their provider. These policies govern coverage and not clinical practice. Providers are responsible for medical advice and treatment of patients. Members with specific health care needs should consult an appropriate health care professional. SPINAL CORD STIMULATION Description: Spinal cord stimulation (SCS) delivers low voltage electrical stimulation to the dorsal columns of the spinal cord to block the sensation of pain. The neurophysiology of pain relief after SCS is uncertain, but may be related to either activation of an inhibitory system or blockage of facilitative circuits. Conventional SCS devices consist of several components: 1) a multi-electrode lead that delivers the electrical stimulation to the spinal cord; 2) an extension wire that conducts the electrical stimulation from the power source to the lead; and 3) a power source that generates the electrical stimulation. The power source (i.e., battery) can be surgically implanted or worn externally over an implanted radiofrequency receiver. Totally implantable systems are most commonly used. The patient's pain distribution pattern dictates the placement level of the stimulation lead in the spinal cord. The pain pattern may also influence the type of device used (e.g., a lead with more electrodes may be selected for those with complex pain patterns, such as pain extending from the limbs to the trunk or bilateral pain). In 2014, the U.S. Food and Drug Administration (FDA) granted 510(k) clearance to the Freedom SCS system (Stimwave Technologies, Inc.) for treating chronic, intractable pain of the trunk and/or lower limbs, including unilateral or bilateral pain. The Freedom SCS system is comprised of an implantable, one-piece, wireless stimulator and an externally worn transmitter to power the device. The Freedom stimulator is much smaller than conventional SCS devices, allowing it to be implanted near the spinal nerves via injection through a standard needle. Implantation of a SCS device is typically a two-step process. Initially, the device is temporarily implanted in the epidural space, allowing a trial period of stimulation. Once treatment effectiveness is confirmed (defined as at least 50% reduction in pain), the device is permanently implanted. Successful SCS may require extensive programming of the neurostimulators to identify the optimal electrode combinations and stimulation of channels. Computer-controlled programs are often used to assist the physician in studying the various programming options when complex systems are used. SCS has been used in a wide variety of chronic refractory pain conditions, including failed back surgery syndrome, arachnoiditis, and complex regional pain syndrome (i.e., chronic reflex sympathetic dystrophy). There has also been interest in SCS as a treatment of critical limb ischemia, primarily in patients who are poor candidates for revascularization, and in patients with refractory chest pain. Definitions: Neuropathic pain: Any disruption (e.g., damage, injury, disease, dysfunction) of the peripheral or central nervous system that results in symptoms such as burning or piercing/stabbing sensations and which is not alleviated by opioids given at clinical dosages. Policy: I. Spinal cord stimulation may be considered MEDICALLY NECESSARY for the treatment of severe and chronic pain of the trunk or limbs when ALL of the following criteria are met: A. Documented history and diagnosis appropriate to this form of therapy, including documented evidence of neuropathic pain; AND B. Documentation that all other appropriate conservative medical and invasive treatment measures have been tried and exhausted (e.g., chronic pain management programs; conservative primary care case management; medications such as anti-depressants, anti-spasmodics, narcotics, antiinflammatories; trigger point injections; nerve blocks and epidural blocks); AND C. Documentation from the patient’s primary care physician or a mental health professional (i.e., psychiatrist or PhD psychologist) that any identified mental health or chemical dependency disorders are being or have been addressed; AND D. Where indicated, completion of a comprehensive physical therapy evaluation; AND E. No medical contraindications to the implantation/spinal surgery (e.g., drug allergies, sepsis, coagulopathy, inability to cope with the technology); AND F. Demonstration of at least 50% pain relief with a temporarily implanted electrode precedes permanent implantation. II. Spinal cord stimulation is considered INVESTIGATIVE for all other indications, including but not limited to, treatment of: A. Critical limb ischemia, as a technique to forestall amputation; B. Refractory angina pectoris; C. Cancer-related pain. Coverage: Blue Cross and Blue Shield of Minnesota medical policies apply generally to all Blue Cross and Blue Plus plans and products. Benefit plans vary in coverage and some plans may not provide coverage for certain services addressed in the medical policies. Medicaid products and some self-insured plans may have additional policies and prior authorization requirements. Receipt of benefits is subject to all terms and conditions of the member’s summary plan description (SPD). As applicable, review the provisions relating to a specific coverage determination, including exclusions and limitations. Blue Cross reserves the right to revise, update and/or add to its medical policies at any time without notice. For Medicare NCD and/or Medicare LCD, please consult CMS or National Government Services websites. Refer to the Pre-Certification/Pre-Authorization section of the Medical Behavioral Health Policy Manual for the full list of services, procedures, prescription drugs, and medical devices that require Precertification/Pre-Authorization. Note that services with specific coverage criteria may be reviewed retrospectively to determine if criteria are being met. Retrospective denial of claims may result if criteria are not met.

Inclusion or exclusion of a code does not constitute or imply member coverage or provider reimbursement.
